Biomechanics behind Atraum atic Forceps:
Atraumatic Forceps work under the "First Class Lever Principle"
One handle of the device is connected to a “bumper,” which acts as a fulcrum during the extraction.
The beak of the extractor is positioned most often on the lingual or palatal root of the tooth and into the gingival sulcus
The bumper is most often placed on the facial aspect of the dental alveolus, typically at the mucogingival junction
No squeezing pressure is applied to the handles or to the tooth. Instead, the handles (once in position) are rotated as one unit for a few degrees, and then the action is stopped for approximately 1 minute.
The torque force generated on the tooth, periodontal ligament, and bone is related to the length of the handle to the bumper (8 cm), divided by the distance from the bumper to the forceps beak (1 cm).
As a result, a force on the handle connected to the bumper will increase the force on the tooth, periodontal ligament, and bone by 8 times. No force is required to be placed on the beak, which is only on the lingual aspect of the tooth root. Therefore, the tooth does not split, crush or fracture
